The context of a proposition consists
of
space, time, view
Each person has his/her own view(s), named
v,
at this time, named t
at time=t, view = v
{...};
The "open web" provides an opportunity to
compare
and merge views.
I take "closed world" to mean facts known at
this time, view.
I take "open world" to mean reasoning about
future facts,
e.g., facts about new instances of concepts which
are
subsumed by a genus-differentia
definition.

just a quick thought without having investigated much
of Kr yet
the system you propose works in a closed world (the diary)
where the representation of the context can be
established a priory and
controlled
in the open web, how would the system capture that context,
considering you have no control over how people number their
knowledge
thanks

what you call "context".

Here's a
thought experiment to explain the nature of "context".

Here's my most fundamental view of
context.
Imagine that I decide to record all my knowledge in a
diary.
Every day, I write propositions in my diary, numbering them 1, 2,
....
Today, I record proposition 123456789; the context of
proposition
123456789 is the list of propositions from 1 to
123456788.
It's that simple!
My KR language and KE program is my
way of
recording, organizing & using a large list of
propositions.

Going from thought experiment back to real
life,
my "context" is the entire contents of my brain.
To make
practical use of this "context" in any particular case,
I can select only
those propositions which are relevant to
the particular case, and I can
use genus-differentia definitions
to summarize the results of many
propositions.
